Synthesis and characterisation of SAPO‐34 with high surface area

SAPO‐34 molecular sieve with a high surface area has been successfully synthesised using Y5669 (N‐[3‐(trimethoxysilyl)propy]aniline) functionalised fumed, silica as the silica source and tetraethylammonium hydroxide as a structure directing agent via a 60‐day crystallisation time. X‐ray diffraction result indicates that the sample is highly crystalline SAPO‐34 and the scanning electron (electron) microscopy images show that the sample is nanosized with a size of ca. 200 nm. N 2 adsorption and ammonia temperature‐programmed adsorption results indicate that the synthesised SAPO‐34 sample exhibits a much higher microporous area and stronger acidity than the conventional SAPO‐34. Moreover, the microporous surface area of the as‐obtained SAPO‐34 can reach 835 m 2 g −1 , which is difficult to realise using other synthesis methods.
